The 69th Infantry Regiment of New York, later redesignated the 165th Infantry, carries one of the most remarkable legacies in American military history. Known proudly as “The Fighting 69th,” this unit is more than just a regiment. It is a living tradition, shaped by heritage, sacrifice, and service. James P. Tierney’s From Dublin to Bull Run to Baghdad and Beyond: The Story of the Fighting 69th traces this history from its beginnings in Ireland in 1848 through the Civil War, the world wars, modern conflicts, and its response to 9/11.
The story begins in Dublin, during the Irish Rebellion of 1848, where dreams of independence clashed with the harsh realities of British rule. Many of those who supported the cause of freedom eventually found their way to New York. There, they carried their heritage into a new chapter of service. It was in this context that the 69th Infantry Regiment was born, rooted in the Irish community and strengthened by the traditions of loyalty, pride, and resilience.
When the American Civil War broke out, the regiment was thrust into action. At the First Battle of Bull Run, the 69th earned its reputation for discipline and bravery. Tierney’s account brings to life the regiment’s early battles, highlighting the heavy losses they suffered and the unyielding courage they displayed. Their performance made a lasting mark, establishing a reputation that carried them forward through generations.
The regiment’s story did not end with the Civil War. As the 165th Infantry, the Fighting 69th served with distinction in World War I, where they took part in the Meuse-Argonne Offensive, one of the largest and most decisive operations of the war. In World War II, they returned to Europe, fighting in campaigns that again tested their strength and endurance. Each conflict added new layers to their history, but the essence of the regiment remained the same. The Irish identity that shaped their beginnings continued to be present in their traditions, their ceremonies, and the spirit they carried into battle.
The modern chapters of the regiment’s service show that their legacy did not fade with time. The Fighting 69th deployed to the Middle East during the wars in Iraq and Afghanistan, proving once again that their role in American military history is ongoing. Tierney also highlights a moment of profound importance to New York itself: the regiment’s response to the 9/11 attacks on the World Trade Center. In that moment of national crisis, the 69th stood with their city, a reminder that their duty was not only to faraway battlefields but to the very heart of the community they represented.
The leaders of the regiment play a central role in this history. From the early commanders of the Civil War to those who led during the world wars and modern conflicts, their guidance shaped the regiment’s culture and carried forward its traditions. Tierney shows how these leaders embodied the values of loyalty and service, ensuring that each new generation of soldiers inherited not just orders but a sense of belonging to something larger than themselves.
What makes the story of the 69th extraordinary is the way it links past, present, and future. The soldiers who fought at Bull Run are those who marched through France, served in Baghdad, and answered the call on 9/11. Symbols like the shamrock still adorn their banners. Songs and prayers rooted in Irish tradition remain part of their ceremonies. Each generation builds on the sacrifices of the last, carrying forward a legacy that is both proud and unbroken.
From Dublin to Bull Run to Baghdad and Beyond offers a full account of this journey, making clear that the Fighting 69th is not only a regiment with a glorious past but also a living tradition that continues today. Its history is built on courage, heritage, and service, and it reminds us that the values that defined the soldiers of 1848 still guide those who wear the uniform now. The Fighting 69th is more than a name in history books. It is a bond that connects soldiers across centuries and ensures that their legacy will endure into the future.
